It is a very common behaviour for us to notice things that we want to look for subconsciously. Like when we just learn a new word, whenever the new word appears again the next few days or weeks we will pay more attention to it and somehow feel that it keeps poping out in our life. Or when we tell ourselves that we need to look for a certain lost item in our room, then we will suddenly find many other things along the way cause we are focusing our attentiont o look for something in the room. This works the same way for how we treat people. If a person gives us a first impression of being neat and tidy, we will often look at the neatness and tidiness that the persons show and further prove to ourselves that he is that kind of person. However, sometimes we might lose out oher important points which actually does not depict so. Same thine when a person gives us a bad impression (example irritating, thereafter everything that person does will be somehow irritating). This is this mentality that actually mislead us most of the time in our lives and make us bias. Therefore, if we tell ourselves that we like this person, no matter what this person does we will think this person is great and good. But at the same time another person might not like him, and thus keep telling himself that alot of things he does is irritating and un-understandable.

Oh well, i guess its impossible to change this. But we actually use this to our advantage. Instead of always thinking of the bad things, we can force ourselves to subconsciously think of the good things. Then we can also try to look out for happy, funny, joyful things in our lives. And not looka t setbacks as demoralising but as a lesson learnt. Then everything will be more positive. Perhaps will we will lead a happier life. I mean our life is already so short, why waste it but being negative all the time?
